Several Kirkwood gaps are found with this group of celestial objects. Kiyotsugu Hirayama noted similarities in this group of objects, and families such as the Themis and Gefion are defined, with Flora being the largest family of these objects. Most members are carbonaceous, silicate, or metallic, and the rare V-type objects were once thought to be from 4 Vesta, the second largest of these objects, which along with Hygiea, Pallas, and Ceres, contain over half the mass of this region.
